St. Louis MO: Boeing has delivered the first four Harpoon Block II missiles equipped with a redesigned Guidance Control Unit (GCU), which provides growth capabilities and resolves obsolescence issues. The missiles were delivered to the U.S. Navy for transfer to two Foreign Military Sales customers.
The new GCU, which controls most of the missiles’ functions, incorporates a Selective Availability Anti-Spoofing Module (SAASM) Global Positioning System (GPS) receiver to improve GPS security. In addition, the GCU can accommodate possible future implementation of a data link for network centric operation.
Boeing began developing this GCU in 2007 to provide a common guidance system for Block II and future versions of the Harpoon missile. All new Harpoon missiles will incorporate the redesigned GCU.
“Boeing’s investment in developing a new, more robust GCU positions the Harpoon program to meet our customers’ needs for many years to come,” said Steve Morrow, Naval Weapon Systems program director for Boeing. “With this upgrade, Harpoon continues to adapt and evolve to meet our customers’ requirements.”
Boeing has delivered more than 7,100 Harpoon missiles to the United States and 28 allied navies and is scheduled to deliver an additional 31 missiles this year.
Harpoon Block II executes both anti-ship and land-strike missions. The 500-pound blast fragmentation warhead delivers lethal firepower against a variety of land-based targets, including coastal defense sites, surface-to-air missile sites, exposed aircraft, port/industrial facilities and ships in port.
